Crystal Pressure Fittings CPF Common Specifications (applies to all CPF fittings in this datasheet)
„„DESCRIPTION

CPF is an improved cone type fitting system that adds a unique o-ring sealing system which permits leak free connections without tools. CPF fittings can be directly connected to ¼" medium pressure cone type fittings from other
manufacturers*, provided that wrenches are used to complete the connection. The fittings of the CPF system have been
designed and tested to comply with ASME B31.3-2008, Chapter IX: High Pressure Piping.
U.S. Patent No. 8,794,677
* HiP: 1/4" Female and Male Medium Pressure (LF4 & LM4 series)
Autoclave Engineers: 1/4” Female and Male Medium Pressure
(SF250CX series)
„„PERFORMANCE
Maximum Allowable
Working Pressure (MAWP): 10 000 psi / 700 bar / 70 MPa
Finger-tight: -20 to 50°C
Wrench-tight: -40 to 150°C
Minimum Hose Bend Radius: 1.0" (25mm)
Thread Type: 7/16-20 UNF 2B
Cone Angle: 60°, nominal
Most fittings thoughout this document meet the MAWP
specificaton of 10000 psi / 700 bar / 70 MPa. Exceptions are
labeled with an icon ( 5 or 15 ) and a key to indicate the
pressure rating.
Internal Hose Diameter: 0.08" (2 mm)

Due to the wide variety of operating conditions it may be subject to, Crystal Engineering, as well as Distributors and
Representatives of Crystal products, do not warrant that this hose is suitable for any specific use. This hose is not for use with
compressed natural gas (CNG).
When used with gases, fuels (liquid or gas) and refrigerants, permeation (i.e., seepage) will occur from inside the hose. In
enclosed or unventilated spaces this permeation may result in high concentrations of vapors which are potentially flammable,
explosive or toxic.
Care must be taken to protect hoses from snagging, kinking, bending smaller than the minimum bend radius, and cutting. Any
hose that has been damaged in any way should be removed from service and discarded immediately.
CAUTION: To achieve CPF maximum allowable working
pressures no o-ring substitutions are allowed.
